First check to see if the for the rest of the focusing scale everything is correct. Then try this:
1. Put a mark on a mirror.
2. Place the camera exactly 1m from that mark and focus on that mark. The distance scale on the lens should read 1m.
3. Focus on the camera. The distance scale on the lens should read 2m.
In that case you should not touch anything.
Also, I would not dare bending anything on my Leica.
